I have done some research and found that when I need multiple passes to cut material, we can get the best results by having a lower power setting for the first pass and subsequent passes set at a higher setting. This first lower power pass creates a guide channel for deeper cuts and reduces burning on the top surface.
Is this possible without creating multiple layered objects?

We all start out that way!
